    Author: Kolev T, Spiteller M, Sheldrick WS, Mayer-Figge H.
    Journal: Acta Crystallogr C; 2006 May; 62(Pt 5):o299-300. PubMed ID: 16679609.
    Abstract:
    Cations and anions of the title compound {systematic name: 1-[4-(aminocarbonyl)butyl]guanidinium bis(hydrogensquarate)}, C6H17N5O2+.2C4HO4(-), are connected into a three-dimensional network by intermolecular N-H...O hydrogen bonds between the L-argininamidium ammonium, amide and guanidinium functions and the hydrogensquarate carbonyl O atoms. The independent hydrogensquarate monoanions are linked into dimers by pairs of O-H...O' hydrogen bonds.
